Abstract

An air conditioning system for use in an over-the-road or off road vehicle is provided that allows operation during both engine on and engine off conditions. The system utilizes a variable speed, motor driven compressor controlled by an intelligent power generation management controller. This controller selects from one of the available sources of power on the vehicle to drive the compressor, and modulates the compressor speed and capacity based on operational parameters and source availability and depletion. The controller may also operate a coolant or air heater to provide heating to the interior compartments.
